Mingus Mill is located just outside Cherokee in North Carolina at Great Smoky Mountains National Park. Mingus Mill was built in 1886 and the turbine was made in in Springfield, Ohio.
My Wife and I have visited the Mingus Mill several times. Unfortunately, the Mill was not operating the last time we where there since the steel pipe leading the water to the turbine was damaged by rust. The total cost for repairs was estimated to $20K. Hopefully, the Mingus Mill will be back in operation soon as possible.
